[NCLUG] printer problems

[rosing at peakfive.com]

I just replaced an HP 855 printer with a 970 and now I'm having
problems with printing color.  It looks like the color portion of
fonts are being squeezed.  So if a string of text has both black and
blue in it the black part is normal but there's a ghost image in
purple off to the side that's the same height but narrower than the
black. 

Ideas?

I found a different driver to use but have no idea how to install it.
What /etc file describes the driver to use?  I assume it's in
/etc/printcap but it's not obvious how to change it.

Thanks,

Matt
